Why do most animals need the endotracheal tube to have a cuff?
|
The cuff creates a seal, w/o a seal:
*the patient doesn't receive proper concentration of gas & can wake-up *the gas leaks and pollutes environment |
|
Who does not need an endotracheal tube with a cuff?
|
*Neonatal puppies & kittens and rabbits (it will tear their trachea)
*procedures that are too short (3-4 minutes: cat neuters); when it takes longer amount of time to intubate than it does for the procedure |
|
What could happen if an endotracheal tube cuff is over-inflated?
|
Tears trachea; (can lead to subcutaneous emphysema or pneumothorax)
|
|
What could happen if an endotracheal tube cuff is under-inflated?
|
*gas will leak out and expose us
*$$$$$-costs increase when gas is wasted *animal will not receive proper concentration of gas and can wake-up |
|
What drug is given to cats to stop laryngeal spasm leading to problems w/intubation?
|
2% Lidocaine topical (use a 1mL syringe w/o needle or a q-tip) used to desensitize the larynx
|
|
What are some complications seen w/incorrect endotracheal tube placement?
|
*Tube can end-up in the esophagus
*Pneumothorax: *Subcutaneous Emphysema: |
|
Pulse Oximeter:
*What does it measure? *How is it used? |
*Measures: how much oxygen the blood is carrying (% of blood oxygen saturation) & heart rate
*Linguinal clip shines a light through a mucus membrane, light reflected off of RBCs determines oxygen % *Linguinal clips problematic * |
|
What are some causes for inaccurate readings w/SpO2?
|
-Poor probe placement or patient movement
-Hypothermia -Hypotension -Tachycardia |
|
EKG or ECG:
*What does it measure? *What does it help diagnose? *How is it used? |
*Measures the electrical activity of the heart--Does not mean that the heart is beating
*SOME calculate Respiration Rate *Helps diagnose arrhythmias |
|
Blood Pressure:
What is it? |
The pressure exerted by the blood against a vessel wall
|
|
Indirect vs Direct Blood Pressure Methods
|
Indirect Methods:
~non-invasive ~Doppler Ultrasound |
